EnableRemoteCommands is deprecated since Zabbix v5.0.2 but we still deploy this config

[anthonysomerset]

In the agent and proxy config templates - we have the following snippet which has been deprecated for some time:

### Option: EnableRemoteCommands - Deprecated, use AllowKey=system.run[*] or DenyKey=system.run[*] instead
#	Internal alias for AllowKey/DenyKey parameters depending on value:
#	0 - DenyKey=system.run[*]
#	1 - AllowKey=system.run[*]
#
# Mandatory: no
EnableRemoteCommands=<%= @enableremotecommands %>

we should probably remove it in favour of replacing with an appropriate AllowKey or DenyKey configuration based on inputs which is already avaiable as config options in the module

i guess this needs a new major version of the module as such a change is potentially not backwards compatible although it would be fairly simple to create some logic to replicate what the zabbix config is doing transparently at this time.
